American society fractures where drug dealers and cops collide, and no one understands the inner workings of this conflict better than veteran narcotics officer, Alonzo Harris. But working America's inner cities to keep the streets clean has taken its toll on Alonzo -- his means are now unorthodox and his methods questionable. Bordering between legal and corrupt, he's about to teach his streetwise ways to rookie cop Jake Hoyt. For Jake, this training day isn't going to be a walk in the park -- it's going to be a gritty, death-defying lesson in underhanded undercover work.
